Oracle Error Message
ORA-23380: propagation mode “string” is not valid
Reason for the Error
The specified propagation may be misspelled, or is not supported. For materialized view sites, all materialized view object groups at the same materialized view site with the same master object group must all have the same propagation method.
Solution
Refer to the manual on replicated data for valid propagation modes. For materialized view sites, also ensure that the propagation modes of all materialized view object groups with the same master object group are the same.
